Speaker: Aji Dhillon (Western) Title: "Quotient stacks as root stacks" Room: MC 107 Abstract: Being a root stack imposes strong conditions on inertia groups. Given a group acting on an algebraic variety I will discuss when these conditions are fulfilled and the resulting quotient turns out to be a root stack. This joint work with Ivan Kobyzev uses some fundamental theorems of algebraic geometry, Abhyankar's lemma, the Chevellary-Shephard-Todd theorem and Luna's etale slice theorem. These results will be introduced. |
